Cannabis Lineage

Cannabis lineage refers to the documented genealogy of a cultivar, tracing its parent strains and breeding history across generations. Lineage records form the foundation of cannabis genetics research, allowing breeders and researchers to understand how specific traits—morphology, terpene profiles, cannabinoid ratios—have been inherited and combined. Major lineage families (such as those descended from Afghani, Thai, or Colombian landrace populations) frequently anchor modern breeding programs. Accurate lineage documentation is essential for reproducibility in breeding work and helps identify which genetic backgrounds consistently produce desired characteristics. However, lineage records in cannabis vary widely in reliability, with some heritage strains having unclear or contested parentage due to decades of informal cultivation and cross-breeding.

Breeders use lineage mapping to make informed crosses, selecting parents known to carry desired traits and avoiding unwanted recessive characteristics. Understanding lineage patterns helps predict offspring phenotype ranges and stability across generations.
